Conclusions

  1. 1.

    It has been established that SPD reduces inelastic strain per cycle for the stress levels studied with any number of loading cycles.

  2. 2.

    As a result of mechanical strengthening the fatigue limit and endurance of steel 14Kh17N2 specimens increased to a greater extent than for steel 20.
